To all whom z't may concern: y

Be it known that we, JOHN PENROSE and 'ERNST A.. Pronenn, citizens ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, havejointly invented certain new` and useful improve ments in Automatic Relief-Valves, of which the following is a description.

Qur invention belongs to that general class of devices known as traps or Water rem` lief valves employed on various` steam or other systems, and `1particularly vacuum steam heating systems, to discharge the `Water of condensation or other fluid from the system without any unnecessary waste or i loss of steam. `The invention has amongits objects the production of aidevice of the kind described that is extremely simple, efficient, durable, and satisfactory, which is entirely automatic in operation, which `Will not be aiected or rendered inoperative by sediment or accumulation of dirt, and one in which the water of condensationor other Huid will not back upthrough 'the system. Other objects and advantages ofthe con` struction will be.apparenttothose skilled in the art, ffronithe disclosureherein given. To this `end ourinvention conslsts inthe novel construction, arrangement and com-V bination `of parts herein shown .fand `described, and moreparticularlypointed` out in the claims.` i l y In the drawings, `wherein like reference characters indicate like or corresponding parts,

Figure 1 is a sectional view through the valve; M l i Fig. 2 is a` sectional View taken substantially on line 1, l of Fi7g `1;

Referring to the drawings, our preferred form of valveconsits of a casing lof suite ablezshape and material provided` with a top "or cover` 2,1 which maybe removed for convenience in constructing or removing the valve and parts thereofn `We havefnot considered itnecessary to illustrate the radiator or vacuum apparatus. Thecasing 1s prof vided With an inlet 3 at one side, which may beformed in the `extension 4, and 1withlan outlet 5 extending through the extension 6,

the extensions being suitably arranged, `for attachment in the "heating system. \Tl1ecasing `Specication of Letters Patent.

is `formed with a depression or pocket be` otherwthevacuum chamber. `The partition is formed with an opening or passage way 9 therethrough. 'lVhile the opening may be placed at any desired point inthe plate or partition,.it is preferred to place it' on;l the side opposite the inlet or intake, as

shown.` l

`lilxtendingbetween the partition `and the outlet is a tubular part 10. the same being so `secured in `place that all water, air, or other fluid, passing or escaping through the outlet must first pass up through the 1opening Qin the partition before passing` by the controlling valveand out through the outlet. The part l() is inwardly extended `and formed with a; valve seat at thei'upper end. 3

In `thecol'istructimi shown thisis formed .in a removable part l1, sothat the part may be renewedjor 4conveniently reground from time to time, as found necessary."` Ve also preferably `form a valve seat 12 onthe un-` l derside of the'transverse part of part`10,'the

purpose 'of which will be more fully ein` plained hereafter: Arranged i to cooperate with the valve seat `in parte` ll is a1 tubular valve memberV .15, `.which is carried bythe tubular member or stem 16,` provided witha lioat 17,.` `llt-ny type oftloat may be em-` ployed,` that shown beingA found: very satisfactory for the purpose. The tubular "stern 16 and parti() in themselves also substantiallyserveas condensing chambers, should therebe any r steam or vapor entering the same. a e i Thevalve and float are guided and limited in their` travel by` a member 18, extending through a suitably sized opening or leakage port -ltin the end of the float Within the conlnient ofthe member. e It is provided with` an end 21 arranged to be engaged by a suitable key or wrench, the same being normally closed by a cap 22, orits equivalent. The cap 22 prevents any leakage ofV steam or water from the casing that may passv between the threads of member 18 and the cover; Arranged in the space of thetubular part :l below the main valve 15, and arranged to cooperate with Ithe valve seat 12, is an auxiliary or check valve 24. This is normally open and carried by a rack 25, or its equivalent, arrangcd'rwith guides 26. The member 24 is intended toseat on the valve seat 12, to prevent any back flow of water should for any reason there be a back'iiow.

Assuming that the valve is closed, as in- Vdicated inthe drawing, and that there is water in the condensing chamber, or below the partition 7 owing to the suction of the vacuum apparatus, any air that might be in the casing is drawn through the opening 14 past the guide 18, and down through the tubular member 16 past valve 24, and through the outlet 5. If there is any air in the system it is drawn through the inlet 3, and through the water, and up vthrough the opening 9, and Ythence through opening 14 past guide 18, and out through the outlet 5. Any steam drawn through the inlet is condensed in the water-in the'condensing cham-V ber..` Thev Vvacuum apparatus Vdraws the water up through opening 9,- but the same. owing tio its weight, is not drawn up over the top ofthe loat.- As soon, however, as the condensation is enough 'and suiiicient water hasV been drawn intothe vacuum chamber of the casing, vor above partition 7, to raise the float, the valve 15 is raised withthe float, and the excess walter flows past `the valve 'and out through the outlet 5. As soon as Vthe valve seats, however, the How is cut off.

' Y Ordinarily all the steam drawn through the condensing water is condensed, but anv steam entering the vacuum chamber, and passing ont through the tubular valve would be insignificant in quantity, and only vapor, as the opening about guide 18is small, and it would be condensed inv thetubular valve stem and in `part `10. The stem or` guide 18 always keeps the outlet 14 or leakage port open. rlhe valve may be positively opened 1 y at any time, or itsY adjustment made bv turningV the guide 18, fthe pin 23 limiting the adkjustment` so thatthe valvemis accurately seated; rlhe .device is entirely automatic and noiseless in operation, and practically can- Y not getout of order.l All the steamis condensed at the valve, `so that practically all available heatunits are extracted substanf tially at the radiator; Should the valve seat v11 wear or ,become corroded, it may be easily replaced or the, ycorrosion removed by regrinding.l

Having thus descrlbed our invention, it is struction, arrangement or combination of parts herein shown and described, or uses mentioned.
